Abstract
L'invention concerne des procédés et des appareils de prédiction inter. Le procédé consiste : à construire une liste de candidats de fusion d'un bloc d'image en cours ; à ajouter des informations de mouvement candidates de HMVP à la liste de candidats de fusion, dans le cas où une quantité d'informations de mouvement candidate dans la liste de candidats de fusion est inférieure à une quantité candidate maximale de la liste de candidats de fusion moins N, N étant un nombre entier positif ; à obtenir un indice de fusion du bloc d'image en cours ; à obtenir des informations de mouvement du bloc d'image en cours en fonction de la liste de candidats de fusion et de l'indice de fusion ; et à déterminer un bloc prédit du bloc d'image en cours en fonction des informations de mouvement du bloc d'image en cours.
